biological approach to behaviour
explanations
ontogenetic
development of structure of behaviour
evolutionary
reconstructs history of a behaviour/structure
physiological
relates behaviour to brain activity
functional
why behaviour/structure developed
evolution of behaviour
genetics
environment and genes constitute behaviour
to what extent to they influence behaviour
personality
sexual orientation
psychological disorders
genes
do not directly produce behaviour
develop proteins that increase probability
under circumstances
indirect affect
heredity and environment
twin studies
monozygotic
one egg
fraternal
two eggs
children within studies
biological parents to infer hereditary
heritability
characteristics dependant on genetic differences
heritability in almost every behaviour
lessened by strong environmental influence
can be used in interventions
can modify PKU
genetic inability to metabolise amino acid
evolution
how do species evolve?
how did they evolve?
offspring represent prents for genetic reasons
heritable variation
microduplications
mutations recombination
change the frequency of genes in populations over generations
artificial selection
selecting desired traits for next generation
behaviours through natural selection
survival advantage
sleep mechanisms
eating habits
life span length
approaches
Chalmers 1995
questions of physics and psychology relationships
relationship of mental activity and the brain
study of physiological, evolutionary and developmental mechanisms of behaviour
brain functioning
microscopic level
gila
neurons
evaluation
animal studies
uses
sheds light on human evolution
unable to use humans
unethical
legal issues
mechanisms of behaviour similar across species
helping/investigating animals
ethics
type of animal used
minimalists
stress induced
abolitionists
animals have same rights as humans
